Abstract：Distributed collaborative air defense is different from centralized defense models, marking a substantial evolution in modern air defense philosophy. It aims to counter increasingly complex and diverse air threats, enhancing system survivability,mission flexibility, strike speed, and adaptability in complex environments. This paper first explored the operational concept of distributed collaborative air defense, reviewing its background and necessity. Then, the requirements for distributed defense from both weapon system and missile perspectives were investigated, and corresponding defensive operational models were proposed. Finally, the key technological characteristics of the distributed collaborative air defense model at both the system and missile levels were examined and identified, giving insights for the future development of air defense missile weapon systems.
